Back then, Bitcoin was 5,000 yuan each. Mr. Li said he would give 100 to Professor Lang. The professor said this thing has no value. He said he would not take it even if it was given for free. Today, the free pi is the same. Others have been developing something for six years without any recognition. You said I can make one in three days. It is really shameless. Pi network will be listed for trading in two days. Even if it is only worth one cent, it is a success. It is not worth one cent when it is born. It took six years to make it worth one cent. When Bitcoin came out, 10,000 Bitcoins were used to buy a pizza. When Pi came out, it was considered a success to use 10,000 pies to buy a pizza. Moreover, the transaction method is simple and convenient, just like WeChat and Alipay, you can pay with one hand and deliver with the other. Then it is the progress of this era. The real digital currency was born, which is also the original intention of Pi!
